To all whom it may comer 1i:

Be it lcnoivn that l, Orro C. Boson, e'citizen of ihe United. Slates, and resident of New: York, in the county and State of New York, have invented an improved Filinil inding Device, of which the following is specification. 7

@ne of the defects in film Winding devices for motion picture machines consists in'ihe fact that the film, after having been 'used in the projecting appsretus,-is so wound up that its front end is located near the center of the reel.

thnshecsine necessary that after winding the film onto the take-up reel inllie customary manner so that'the front end of the senieis near the center of the-reel, to rewind the same ontonno'ther reel, in order to get the front end of the film onthe outside of the reel. v i I Elioris have been made to eliminate reivinding and the present invention is intended to provide a simple, inexpensive de vice wherein this object is accomplished. This is brought about by constrnciing an organization of sistionnry parts, including radially .or tangentially and resiliently disposed rollers, and an organization of rototzilile parts, to which the front end of the film is appropriately secured, cooperating the with the stationary parts so that the film,

it leaves the projecting apparatus, may be directly Wound so that its front end. is on the outer periphery of the reel and ready to be reused in the projecting apparatus of the motion picture machine, Without the necessity of rewinding the same.

The drawing illustrates the invention in Figure l, in an elevation and, in friars, in cross section of the organization of the stationary parts. Fig. 2. is a vertical transversnl cross section in the axis of thedevice, Fig 3, l 21nd are views, in part in cross seclion, of the rollers, and 6, is a view of the front end of the film.

A. base 1. carries-n bracket 2, for supporting a stationary plate 3, having a portion cut away, 15 m 4-. A mandrel 5, is secured to the plate 3. and provided with a key 6, for preventing rotation of a plug or cylinder 7. This cylinder is surrounded by a sleeve 8, also secured to the plate 3, and a second similar, but enter sleeve 9. A nhrnher of spring barrels 10, preferably oficylindricsl shape, are secured to the inner sleeve 8, as Well as to the outer sleeve 9, and

tangentially disposed and spirally distributedelong the :25, so that they may be of considerable lengih. and firmly held in plac Each of the barrels contains a, helical spring 11, surrounding a, rectilinearly recip roeeliohlc rod i2,"provided with a collar 13. (lne end of the spring'resicgainst the hotilOi'fl of the barrel and the other end zig'ainsi the collar 13. In order to prevent the rods leaving she barrels, the latter are provided with a flange 14-. The means for assembling the barrels and the rods is of no importance and does not form part of the present invention. Each rod carries or is extended into a roller shaft 15, in some cases secured to a bracket 16. There are five rollers shown, the

number of which may however be increased or decreased, es desired. The rollers 17, are prei'erabiy disposed as shown. in Fig. 2. roller, such. as the. one shown in Fig. l, is

in Trig. 5, to the left of and adjoining the firs; roller, 2; third roller, suchas shownin 3, so the leftof and adjoining the second, roller. a fourth, similar to the one shown in Fig. 5, hot reversed in position,

'to lghe left of and adjoining the third roller,

and e fifth, similar to the one shown in Fig. 4, lint reversedin position, and Without the. film guide. to the left of and adjoining the fourth roller, The operative position of the roller shown in Fig. 3, is indicated in dotted lines, as a circle Within the roller. the isosition of the roller shown. in solid lines, is only intended to more clearly illusirate the relation of the roller toics holding" means. The rolleron the right hand side of'Fig. 2, and on the top of Fig. 1, is provided with a. film guide 18, receiving the film 19, from any suitable outside source, such as a mot-ion picture projecting machine, and for leading the shme onto the relaining rollers. Y i

The loose or rotatable members of the device, comprise the plate 20, supp'ortedbv 3nd rotatable on the mandrel 5, and held thereon by a nut 21, or other suitablemeans, It may be rotated by any convenient means, such as a crank, gear, etc. This plate carries acylindrical mantle or detachable flange preferzibly made or parts hinged together, at two points diametrically opposite, one of the points provided with locking, means, which mantle is secured to the plate located on the right side end adjoining" the plate 3,.another roller, such as shown 20, by convenient fastening means, such as the thumb vscrews The mantle is provided with flanges 2i. surrounding the out-er edges of the stationary plate 3, as well as of the movable plate 20, and is movable, of

course, with the latter. The mantle is provided on its inner side with a button 25, or other device, for receiving the opening 26, of the front end of the film 1!).

The operation of the device is, as follows: The film 19, as it comes from the projecting apparatus of a motion picture machine, or from some other source of supply, is carried through the slot of the film guide 18, and then secured with its opening 26, to the conveniently positioned button '25, of the mantle In now rotating the loose disk 20, the lilm is so wound against the inner side of the cylinder, that it forms the outer layer of the reel. Any succeeding layer will .-be rolled onto the inner side of the preceding outer layer and forced thereon by means of the resiliently supported rollers 17, until the entire film is wound up, and the springs 11, compressed to their limit. In re-using the film, or unwinding the same, the mantle 22, is taken oft the plate 20, the outer film end removed from its holding button 25, and the film reel placed again onto the take oft reel of a projecting machine.

Claims.

1. The combination with a rotatable memher having means thereon for holding the end of a film, of a stationary cylinder arranged coaxially with said member, a series of barrels arranged tangentially on said cylinder, a spring controlled rectilinear-1y reciprocatable rod in each barrel, and a roller at the free end of each rod adapted to guide said film during the rotation of said member so that successive windings of said film are located'on, and in contact with the inside of the preceding Winding.

2. The combination with a rotatable member. of a detachable flange thereon, means on said flange for holding the end of a film, a stationary member arranged coaXially with said rotatable member, a series of barrels tangentially arranged on said stationary member, a spring controlled rcctilinearly reciprocatable member in each barrel, and a roller at the free end of each reciprocatable member adapted to guide said film during the rotation of said rotatable member whereby succeeding layers are placed within preceding layers of said film.

3. The combination with a rotatable member, of a detachable flange thereon, means on said flange for holding the end' of a film, astationary member aranged coaxially with said rotatable member, a series of barrels tangentially arranged and spirally distributed on said stationary member. a spring controlled rectilinearly reciprocatable men1- her in each barrel, and means at the free end of each reciprocatable member adapted to guide said film during the rotation of said rotatable member whereby succeeding layers are placed Witl'llILPlQCQdiDg layers of said film.
